  1. In case anyone can help, I need a copy of the March 2004 issue of Elektor
    Electronics magazine (Nr 330), to complete a break in a library sequence.

    I will of course pay for the copy plus postage.

    Please help if you can.

    Sorry I can't help - just replied to say 'my god, it that still going!'

    Elektor used to be my favourite as a 'yoot' doing electronics as a hobby
    in the 1980s when I got fed up with Hobby Electronics and ETI.

    I have some of their 30x circuits books somewhere - they always came up
    with a circuit idea when I needed something.

    Hi!

    To add to your anguish, I just looked at the only two copies of Elektor
    I have.

    They are Febuary and April 2004 :-(

    Yours, Mark.

    Amazing, I also didn't realise that they're still going, even though I have
    a loft creaking under the weight of ancient copies.

    However I actually found a use for one of them a few weeks ago, when the
    starter in the fluorescent lamp in my garage failed and I didn't have a
    replacement.

    I remembered that there was a small circuit for an starter using a thyristor
    (which I have dozens of) so after a long search the appropriate magazine was
    found and the circuit hastily constructed on a piece of Veroboard, worked a
    treat and the tube now springs into life instantly!

    Going slightly OT now but you really should replace the tube as well
    as the starter as a worn out tube will put additional strain on the
    starter. It is also recommended that flourescent lamps be replaced
    every 12-18 months as they lose a lot of their light output and
    electrical efficiency by that time and will gradually do so till they
    fail, unlike standard incandescants which either come on 100% or don't
    come on at all.

    Sure Elektor is still going! Just bought a copy recently when I was in
    Germany. It is every bit as good as it always was.

    Actually I resuscribed again this year, I still have the first issues from
    1972 or so, but I never opened them again, they are stored somewhere in the
    basement. If some offspring continues my way, he could one day find these
    mags and reread them. Well, my eldest son(29) is just doing his PhD in EE.
    You are right, lots of interesting things inside, much better than Circuit
    Cellar, which is defined to PICs and alike.

    In practice, everyone, including all places where I've worked, waits
    till the tube completely dies.
    Regards Mike.
     
  10. It will obviously depend on its use. If you're using them for an important
    application, then it certainly makes sense to replace them regularly -
    although how often will depend on the amount of use, the type of tube and
    the type of ballast. Modern high frequency types are far kinder to the
    tube than switchstart ones, as well as more efficient.

    If all it's doing is lighting the stationary cupboard, then as you say
    most wait until it fails. Which can be a very long time.

    Well yes, I did say recommended! ;-)
     
  12. Back in the '70s I managed apts for a guy who worked at
    McDonnell-Douglas, in Long Beach, CA. He would go to the surplus sales
    and buy a whole carton of 4' or 8' fluo tubes. The maintenance guys
    would sweep thru the bldgs with ladders or cherry pickers and replace
    every tube in every fixture, because since they were union and labor
    cost so much, it was cheaper to just replace everything at one time, and
    of course it also gave brighter light.

    He would bring a carton of used tubes to the apts and most of them would
    be just fine, since they had been installed just a year earlier as
    replacements.
    I don't know if they still do this, but it makes sound economic sense,
    obviously.

    That must be a universal practice, as several years ago an electrician
    friend gave me about a dozen perfectly good 4' tubes which he had acquired
    for the same reason, i.e. companies blanket replacing them at set intervals,
    irrespective of whether it was needed or not.
     
  14. My government office has stopped doing sweep replacement - someone did
    the sums and they didn't add up.
     
  15. Lurch

    Lurch Guest

    If we all did some sums then it probably wouldn't be worth any of us
    actually going to work so we'd all be at home on the rock n roll so
    there wouldn't be any lighting used in offices, and if there were
    there'd be no-one to come in and refit them.
     
  16. I ever worked in an airforce hangar. Changing a tube was a hell of a job
    that interfered with the ongoing maintenance tasks. So if the percentage of
    failing lamps raised above 2% (if I remember well) they planned a day to
    replace all tubes at once.

    BTW, where can I find the starting circuit mentioned in the original post?

  17. Was it out-of-stock from the Elektor "back issues" service ?`
